WASHINGTON, July 20– Children between the ages of 10 and 19 can transmit COVID-19 within a household just as much as adults, reported Xinhua news agency, based on new research published in the U.S. Centers for Disease Control and Prevention journal Emerging Infectious Diseases.
Researchers from the South Korea Centers for Disease Control and Prevention analysed reports for 59,073 contacts of 5,706 COVID-19 index patients reported in South Korea during January 20 to March 27.
Of 10,592 household contacts, 11.8 per cent had COVID-19, and rates were higher for contacts of children than adults, according to the study. Of 48,481 non-household contacts, 1.9 per cent had COVID-19.
Researchers also found the highest COVID-19 rate at 18.6 per cent for household contacts of school-aged children and the lowest at 5.3 per cent for household contacts of children 0-9 years in the middle of school closure. “Rates were higher for contacts of children than adults,” said the authors. “These risks largely reflected transmission in the middle of mitigations and therefore might characterise transmission dynamics during school closure.”
